Investment Casting-Bearing Seat

Wecare Precision Cast Parts uses this process exclusively. Wax is injected into an aluminum die casting to create a wax "pattern". These wax patterns are then assembled onto a "tree" which is repeatedly dipped in a ceramic slurry that, after drying, hardens into a mold. The wax is melted out, the mold is preheated and the metal is poured in. The resulting lost wax casting has an excellent surface finish of around 125 RMS, crisp lettering and minimal machine stock. This process is perfect for highly visible or highly machined parts. Tolerances can be held to +/-. 005" in most cases.
